Selective GPR84 Antagonist

Selective G-protein coupled receptor 84 (GPR84) Antagonist

GPR84 is a pro-inflammatory target primarily expressed on cells associated with the immune system and its expression levels increase significantly during periods of inflammatory stress. Inhibition of GPR84 can inhibit neutrophil and macrophage migration and reduce cytokine release.

However, GPR84 expression is not restricted to cells in the immune system; it is also expressed in tissues such as the brain, heart, muscle, colon, kidney, liver, intestine, adipose and lung. Through its role in inflammation, GPR84 may be a mediator of the relationship between inflammation, obesity and diabetes. Rodent models suggest that GPR84 expression is up-regulated in adipocytes in response to TNF-α released from infiltrating macrophages, and that this in turn can lead to a down-regulation in adiponectin expression in adipocytes. Adiponectin is known to have anti-diabetic, anti-inflammatory, and anti-atherogenic effects, and it also functions as an insulin sensitizer.
